David Duffield is the Eurosport commentator for English speakers (or at least he was....been out of the loop for a while!). If you watch the SBS 1 hour Worlds highlights, it's often him doing the talking. When he gets excited, it just starts flowing out....we are always only minutes away from hearing about his record tme from Lands End to John-O-Groats on a tricycle again....
Sean Kelly was his co-pilot for a while....talk about chalk and cheese. One's a blubbering dandy who has more trouble identifying riders than Phil Liggett with Vaseline smeared on his glasses.....the other is the quintessential hard-man who speaks only when necessary.
But I guess when Sean Kelly talks cycling, you listen.
